Nothing to explain here.
Use bloodmage talnos with various spells, like defile for boardclear, mortal coil for draw a card, drain soul for heal and remove early game threats. You can use drain soul + defile to clear multiple minions turn 4. Use your doomsayers on empty board after board clear or turn 2 vs aggro decks.
Chittering tunneler can give you an additional copy of any removal you need.
Orince valanar a strong anti aggro mid game minion, which can help you with sustaining pressure or give an additional heal mid game. And its a taunt
The goal of the deck is playing as much demons as you can and try to survive until turn 10, when you can use your ultimate Bloodreaver Guldan and summon all of killed demnons instantly. The hero power is good for pressure and heal.
I did this deck just for me, but if anyone else intrested in this, i’ll made a guide after release and continue to do other decks.


















Why not run Treachery if you’re running doomsayer, guarantee’s it will go off. Just a thought.
Yeah, treachery can be good, but i think run this card just because of doomsayer is not worth it, because card by itself do nothing. But if you need, you can discover it from Tunneler.
